Epcoritamab Combo for Relapsed Follicular Lymphoma OK’d

Share

FDA has approved Genmab’s Epkinly (epcoritamab-bysp) for combination with lenalidomide and rituximab in adults with relapsed or refractory follicular lymphoma (FL), expanding treatment options for one of the most common indolent B-cell lymphomas. The agency action also converted the drug’s 2024 accelerated approval for third-line FL into a full, traditional approval, allowing epcoritamab to be used as a standalone therapy after two or more prior systemic treatments.

The combination regimen’s approval was based on data from the Phase 3 EPCORE FL-1 trial, which enrolled 488 patients with relapsed or refractory FL who had received a median of one prior line of therapy, according to an FDA notice. Nearly one-quarter had undergone at least two prior treatments.

Patients were randomized to receive either epcoritamab plus lenalidomide and rituximab or the standard lenalidomide and rituximab regimen alone. FDA says the study demonstrated a dramatic improvement in progression-free survival (PFS):

  • PFS hazard ratio: 0.21 (79% reduction in risk of progression or death)
  • Overall response rate: 89% with the epcoritamab combination vs. 74% for standard

The agency notes that Epkinly’s updated prescribing information includes Boxed Warnings for cytokine release syndrome (CRS) and immune effector cell–associated neurotoxicity syndrome (ICANS), two known risks with T-cell–engaging bispecific antibodies. In the EPCORE FL-1 study:

  • CRS occurred in 24% of patients (serious CRS in 12%)
  • ICANS occurred in 0.8%
  • Serious adverse reactions occurred in 51% of patients receiving the epcoritamab regimen
  • Serious infections were reported in 28%
